Contenders for the start of the Renaissance era:
p/6918779: Annual "What did OT get for Christmas" event
^ This would cover the creation of the Shitpost Thread and my introduction of 𝓢𝓚𝓘𝓛𝓛, which opened the A-Breaking Laboratory vs Ashton Co. arc. Conveniently marks it around the start of a new year.
p/6956061: OT Court II: A-Breaking Laboritory & R.O.S.Q. vs Asht. Co
^ This is around the time it starts to actually feel like things are changing and not just me and Ashton messing around. Full involved from denizens indicate a change of pace in OT
p/6966183: A snapshot of everyday life in the parallel OT dimension
^ Definitely Renaissance era at this point, and the end of OT Court II marks it as if OT has finished metamorphosis.
